I 'Ihis invention relates to new and useful p I i I V of the'tunnel member. Parallelspacedverimprovements in flying machines. I

V The invention hasforan object the provision of a device of the class mentioned, which is of simple durableyconstruction, de-

sirable in use and efiicient' in action and which may be manufacturedand sold at a reasonable cost. The. invention proposesa tunnel member g 0 in an aeroplane body and of smaller rear ameter than front diameter and connected with main wings and with parallel vertical rearward extendingwalls supportinga hori zontal tail wing, a motoredriven propeller to be mounted in the rear of the tunnel member and arranged for adjustment along the axis of the tunnel member, both propeller and tunnel member being slightly flared. For further 1 comprehension of the invention, and of the objects and advantages thereof reference will be had to the following'description and accompanying drawings and to the appended claims in which the various novel features of; the invention are more In the accompanying drawing forming a material part of this disclosure I i Fig.1 is a front elevational view of aide,-

Fig. 7 is a plan view of the device. I

V The reference numeral 10 indicates generally a tunnel member having a rear opening and a much larger front opening. A pilots chamber'll isattached uponthe. tunnel member and extends to the! front thereof. This pilots chamber is of smaller width than V the tunnel'member so as to provide air passagesat the sides shown in Fig. 1. Aseat 12 is arranged within the pilots chamber and a pilot 13 isshown occupying the seat.

ing' the sections 7 6 relative to Fig. 2 is a vertical sectional view taken on Main wings 14 are attached, upon the sides tical walls connect with the rear portion of'a tunnel member and extend materially to "the rear... These walls are reinforced byhori-,

zontal ribs 16. A horizontal tail wing17 con ne'cts with-the rear portion of the Walls 15 The outer tips 18 of the main wings are separate from the other portions and arehi-nged- 1y connected as et 19. 6

The verticalfwalls 15 are each formed'of two separatesections 7 6 and 7 7 respectively.

Sections77 are stationary and sections 76 movably connected withthe stationary sec-.

tions. .Th movable sections have projecting tongues 78 engaging in corresponding grooves 3 These sectlons in the stationary sections. connect with each other onthe arcs of a cirlcle solthat the movable sections may be rotated relative to the stationary ones. Aperture's 9 are'extended thru the stationary sec tions and thru the. tongues 78 and bolts 80 engage certain of these apertures for holding the sections in a relatively fixed .position. Thelinclination of the tail Wing17 may be adjusted by removing the bolts 80 and rota-tthe sections 77,' then reengaging the bolts.

One of the hinged sections 18 connect with able by the pilot, the other of the'wires being wound upon the drum in the'opposite direction to the'first wireso' that when the pilot tur'ns'the steering rod 23 in one direction the wing section 1,8-wi1lbe-moved upwards and when the steering rod is turnedin the opposite direction the section; I will be moved downwards.

, The vother hingedsection18 is similarly connected with wires 20' and 21" engaged upona drum 22 mounted'upon a steering rod 23' also operablebythe pilot. This arrange; ment l permits individual control ofthe sections 18 on. the ends of; the main wing. i In .planyi'ew asv seen .in Fig. (the inner ends of the'sections l8 are adjacent the outer ends of the main wing. and the lines of contact are inclined from the front of the machine diverging towards the'rear.

A curved passage 24 passes thru the tuni' 'ne'l member and an adjustable top vane 25 with air channels 26 engages in the top of the curved passage. Within the passage,

central and bottom vanes 27 and 28, re spectively are stationarily mounted. These vanes are provided with air elia-nnels The air channels increase the operating sumfaces of the vanes. The top vane 25 is fixed 7, upon a shaft 29 provided with a worm 30 meshing with a worm pinion 3 1 upon a shaft 32, The shaft 32'is rotati'vely-rnounted and extends within reach of the pilot. A

The motor 37 is provided with lngs 81 "threadedly engagin gsjcrews82. "These screws & "are rotatively mounted "in standards 83 attach'ed 'wi'thin the tunne l memoer 10. A sprocketfwheel 84 is fixed upon the screw "82 and connects with a sproelzetzchain 85 conn cting with another sprocket wheeliB6 upon a shaft 87. This shaft extends within reach 1 of the'pilot of the machine an'd'is provided Aiork89isfiXed-upon one ofth'estandards 83 and engages a :co'llar9O slid'aldly mounted upon a square :sect'ionQl ofthe 'sThaft of the motor 37. pulley "92is connected with 'the collarQO antlis engage'd rby the'said *belt 36. The tips of the propeller are fflaretl as indicated b'y reference numeral .93. The rear end aoi? the'tu'bular meniberlO is correspondingly flared as indicated by reference numeral 94.-

"The'ihand whee1i'88 maybe rotatedfor movfj n'g ith e mot-or L37 slightly forward or 'rear itance between the flaredtips o'fgtheipropeller "and the flared end of the tubular meniber.

Front wheels :44 engage upon the front nf'the wing 39randrear fsprin'gsf45 "upon'the -rear oftlrewing. These "S'JIIIIgS are firmly connected "withwertical pegs 46. These pegs have slots 47 engaged by transverse shafts 48 supporting rear wheels 49. The wing 89 has an opening 50 permitting the peg 46 to move upwards if the springs 45 flex during landing.

' A maclrfil is slidably mounted in the pilots chamber and connects with a spring '52 conne'cte'd'with the wing 39. The rack 51 meshes with a gear '53 on a shaft provided with a worm -wheel The worm wheel meshes with a worm pinion 55 upon a shaft 56 1'0- izatinely mounted and provided with a collar 57 having a plurality of peripheral apertures. The snare 56 is connected by bevel gears 58 to a steering rod 59 arranged in the vicinity of the pilot and provided with a steering wheel 60. A 'latlch' 61 is arranged to engage in the apertures of the collar 57 for latching "the shaft "56 against rotation. The 'latch '61 is connected by a link 62 with a lever 'l'atch63i' V I a 'Th'e'tunnel meinberlfl is provided with side wings 64 fixed upon arbors '65 arranged for rotation :Sprocket wheels 66 are attached uponthe arbors 6'5 andcon'nect'with sprocket chains '67 lengagingupon sprocket wheelsiGS. The spro'cket'wheels 68 are fixed upon shafts rotatively mounted and provided with gears 69. jThesege'ars mesh with smaller gears 70 coimect'ed'with a handle 71 -for manualrotation. Aspiring pawl 72 is arranged fol-latchthe car 70 against rotation. Atop fin is provide "upon the main wings '14 and consists :o'ia ear section 73 and a front section 74.
